MATTRESS-FILLING MACHINE.

Application filed February 17,1926. Serial No- 88,794.

The present invention relates to an improvement 1n mattress fillingmachines.

The ob ect of the invention is to reorgan ize and improvemattressfilling machines,

5 and to this endthe invention consists in the machine hereinafterdescribed and part cularly defined in the claims.

The accompanying drawing illustrating the preferred form of; theinvention is an elevation. 2' I a The filling mater al, such as kapok,IS introduced in the hopper 10, from which it passes through the pipe 11to the blower 12. This blower discharges through the riser pipe 13 andpipe 14; into the tank 15'. The

pipe 14 is a horizontal conveyor, pipe, provided in its lower side witha w1re'screen'.

16, which allows any dust or stems or dirt to pass through into the dirtbox 17 V A door 18 on the front of this dirt box is provided to enablethe dirt to be removed.

wvided which extends aroundthe lowerpor-' tion of the tank below thebeater through which dirt and refusesuch as stones, sticks and the likemay pass into the dirt chamber 24;. Doors 25 areprovided for permittingaccess'to the dirt chamber 2 1 to remove the dirt therefrom.

The tank 15 is connected by a throat 26 with a second tank 27. In thethroat is a damper 28 by which the tank 15 may be closed so as to retainany material being treated in the tank 15. The material passing from thetank 15 through the throat 26 into the lower tank 27 is again subjectedto the action of a beater 29, which cooperates with grate bars 30,having fingers arranged radially of the beater arms of the beater 29, soas to further treat the fibre being operated dirt to collect in the dirtchamber 32, a door At the advance end of the dirt box is an openpock- Asimilar The tank 15 comprises a large 33 being provided for access tothis. dirt chamber to clean it.

The material, after being beaten in the lower tank, will be withdrawnthrough the pipe 34 and carried through that pipe to the blower 35, adirt box 36 being provided on the lower side of this pipe like theedirtbox, 17 above described. material .is discharged through the riser pipe36" into the horizontal pipe 37, similarly provided with a dirt box 38.This pipe is provided with an air intake netting 39 in itstop,throughwhich air may enter the pipe 37 when demanded by theoperation of the machine.

Aflap damlower part of the pipe 40v leads backto the v pipe 34. A damper43 is provided in the .pipe 34, and when it is opened, material fromthe; lower tank 27 is carried from that tank into the fan35.

The tank 15 is provided at its top with,

a wire netting closed cover44 to permit the entrance and emission of airfrom the tank to the interior of the tank for the purpose of cleaning itand removing any collected.

material from the beater. A similar door 467 is provided in the topofthe lower tank 2 I The operation of the machine is as follows: Themattress filling material, which is kapok, feathers, or what not, isintroduced into the receiving hopper 10, carried to the blower 12, andthence discharged into the again closed, and the upper tankwill bein acondition to receive another supply of l3 leading to the lower tankwill. be opened and the material therein will be drawn out by the fan85, admission of air to the lower tank being provided by the screencover opening 47. t'lhematerial thus discharged into the blower fan 35will he carried by it to the nozzle 41 and discharged into the mattrUpon completing the filling of a mattress-the damper l2 will be swungfrom the position shown, to a position closing the nozzle, and suchmaterial as is in the mattress filling system shown at the left of thedrawing will be permitted to circulate through the fan until anothermattress is ready to receive the material therein.

The machine is adapted to subject the filling material to three cleaningoperations by carrying it over the three dirt boxes in the threehorizontal legs or lengths of the conveyor piping. Thematerial lirst putinto the machine will be carried immediately to the upper tank whichwill at that time be separated from the lower tank by the closure in thethroat, and will there be subjected to a preliminary beating operation.

Then this material will be dumped into the lower tank and subjected to afurther heating operation at the same time that a second charge is beingreceived in the upper tank tanks, a heater in each tank, means "fordelivering material to the upper tank, a connection between the tanks topermit material to fall by gravity from the upper to the lower tank fora secondary beating operation in the latter while a fresh charge isbeing simultaneously beaten in the former, a closure in the connection,a blower, a pipe leading from the second tank to the blower, and adischarge pipe connected with the blower.
